A lab instructor performs an experiment using an aluminum cup that contains 225 g of water and a 130 g copper stirrer, all initially at 27.0°C. (Note that the student wears insulated gloves when handling the stirrer.) The lab instructor then adds a sample of silver to the water. The sample has a mass of 446 g and is initially at a temperature of 85.0°C. After stirring the mixture until it reaches thermal equilibrium, the lab instructor measures a final temperature of 32.0°C. What is the mass (in g) of the aluminum cup?

An aluminum cup contains 225 g of water and a 40-g copper stirrer, all at 27°C. A 467-g sample of silver at an initial temperature of 90°C is placed in the water. The stirrer is used to stir the mixture gently until it reaches its final equilibrium temperature of 32°C. Calculate the mass of the aluminum cup. 356 x Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. g
You drop an ice cube into an insulated flask full of water and wait for the ice cube to completely melt. The ice cube initially has a mass of 90.0 g and a temperature of 0°C. The water (before the ice cube is added) has a mass of 890 g and an initial temperature of 24.0°C. What is the final temperature (in °C) of the mixture? (Assume no energy is lost to the walls of the flask, or to the environment.) °C

I am very hungry, so I need to cook myself some ramen on the stove. I fill up a pot with 2 kg of water and place the pot on my stove which has an average power output of 8.22 kW, raising the water's temperature from 31.5°C to its boiling point (roughly around 100.6°C). How long after placing the pot of water on the stove does it take for the pot of water start boiling in seconds? Hint: Water has a specific heat of 4.2 k J k g ∘ C, and this is an energy transformation problem. Start with finding Q.
